Neitz & Holland have one year left. Miller hasn't proven he's in our best 22. I don't see Dunn as a FF/CHF-type in terms of build, and it seems we might want to use him in a utility role a la Bruce.
Who does that leave us with? Robertson, who's an ageing third-tall with a future up in the air, and youngsters Bate & Newton. Hardly an embarassment of riches.
I wouldn't say no to a forward. That said, I don't know about McGregor.
